To all mam-1; may concern;

Benimqwn that 1, PAUL citizen of the United State re siding a Carlstadt, in the county of Bergen State of ,7 Jersey, have invented a certain new and useful Improvement in Supports for Heddle-Bars, of which the following is a pe ifi ti n- T e d iv ntio re ates to t .lOOPS y ch i h l b r ar support dbetw e the harness shafts, and the object of the in A. Written, a

Figure 1 is an elevation ferred form of the support in service. Fig.

2 is an elevation on a larger scale showing one face of the same support engaged with a shaft and bar. Fig. 3 is a corre sponding view of the opposite face. Fig. lis a vertical section taken on the line fi -fir in Fig. 3, showing the support in side view. Fig. 5 is a vertical section on the line 5-5 in Fig. 3. Fig. 6 is a horizontal section taken on the line 6-6 in Fig.2. Fig. 7 is an elevation corresponding to Fig. 1 but showing a modified support. Fig. 8 is an elevation of the modified form with a portion of its shaft and bar. Fig. 9 is a vertical section taken on the line 9-9 in the preceding figure and showing the support in side view. Similar letters of reference indicate like parts in all the figures.

Referring to Figs. 1 to 6 inclusive, A A are the shafts forming part of the frame and supplied with the usual harness, not shown, B B are the heddle bars and C G the leashes or heddles, all of which may be of any ap proved forms, D D are the heddle bar supports, arranged in pairs on the upper and lower shafts, each pair supporting a heddle bar B. I

shb'tiii g the ere Fach support is the counterpart of the other and a description of one will suffice.

Itcomprises a strip ,or length of resilient material preferably spring. metal bent to form the body portion D inclosing the shaft A, and itsends continued in the form of straight parallel arms D D adapted to be forced together in opposition to the spring of body portion which tends to separate themfias indicated by the dotted lines in Each arm is slitted .on lines parallel with its edges and the metal forced out of the plane'of the arm .to form a single intermediate loop D on one face and two outer loops D D on the other face, and .the loops D Dtof both arms are on corresponding faces and so shapedthat when the arms are forced together in clamping the body portion D upon the shaft A the two loops D and the four loops D? match or nest together to pro vide a composite opening (I in which the heddle bar is. received. The bar is thus in closed and friotionally grasped and is held strongly enough to prevent unintentional endwise movement but may be shifted in the supports as desired in grouping theheddles by exerting sufficient force to overcome the. frictional resistance.

D D are spurs on the inner faces of the body portion D adapted to be forced into the wood of the shafts to maintain the support in position when closed thereon.

The heddles G C are looped upon the bed dle bars B B in the ordinary manner and may be spaced, grouped and located as usual.

By reason of the single loop D on one face of each arm D lying between the loops D D on the other face, and the nesting of the loops of one arm with those of the other, the arms are securely interlocked by the introduction of the bar B, and the torsional strains of the arms tending to bend or distort the bar or twist the body portion D upon the shaft are eliminated, thus permitting the bar to lie straight and in parallelism With the shafts and companion bar.

In the support shown in Figs. 7, 8 and 9 the body portion D is similar to the form above described but the arms D D are given a quarter turn, as at D to extend parallel with each other and face to face transversely of the shaft. The arm D is straight beyond the twist D and the arm D is folded upon it to form a loop or bight D inclosing the end of the arm D thus'providing three thicknesses of the metal. All are pierced as at (Z to receive the bar B which is thus held and subjected to the frictional tension supplied by the tendency of the arms to separate angularly.

By engaging the bar at two separated points in the folded or double arm D and also at a point between in the straight or single arm D the torsional tendency of the arms to spring or distort the bar is avoided in the same manner as by the engagement of the single loops D between the flanking loops D D in the form first described.

Any suitable material may be employed for the supports and the proportions may be varied to suit conditions of service. vThe bar may be cylindrical or of other cross-section with the loops correspondingly shaped to receive it and the support may be formed of wire bent to inclose the shaft and form the desired loops. Both forms of the device as illustrated may be easily and cheaply manufactured, applied and adjusted.

I claim 1. In a heddle bar support, a length of resilient material bent to form an open body portion adapted to inclose a harness shaft,

and having arms shaped to lie together and receive and be interlocked by the introduction of a heddle bar therethrough, said arms 7 arranged to grasp said bar at two separated outer points thereon and at an intermediate point and hold said bar frictionally against longitudinal movement, without transmit- Gopies of this patent may be obtained for-five cents each, by addressing the Commissioner of Patents.

ting torsional strains of such arms to said shaft and bar.

2. In a heddlenbar support, a length of spring metal bent to form an open body portion adapted to inclose a harness shaft, and having arms arranged to lie face to face, each of said arms having a single loop on one face intermediate a pair of loops on the opposite face, the loops of one arm constructed to nest with the loops of the other arm and receive a heddle bar thrust through such nested loops, and hold said bar frictionally in opposition to a longitudinal movement relatively to such support.

3. In a heddle bar support, a strip of spring metal bent to form an open body portion adapted to inclose a harness shaft, spurs on said body portion adapted to engage such shaft, said body portion having arms formed integrally therewith and adapted to lie face to face, each of said arms having two slits parallel with its edges, with the metal between such slits bent out on one face to form a loop, and the metal on each side of such loop bent out on the opposite face to form two loops, the loops of one arm adapted to nest with those of the other and receive a heddle bar thrust throughsuch nested loops.

In testimony that I claim the invention above set forth I aflix my signature, in presence of two Witnesses.
